I have a Cloudray C Series head and mirror mounts. When cutting, I focus around 6mm off the surface. I need to expand that distance for tumbler engraving.
I’m unsure if I can use the focal lens my head came with and just move it within the tube, or I need another lens to increase focal distance. If I need another lens, which that’s the direction I’m leaning, which lens do I need and in what position will it be placed in the tube.
Hoping the screenshots help explain better. Thank you
I use C series tubes from Cloud Ray, but use a totally different head… however the lens functions the same on all of these.
The normal lens is a 1.5" or 2" depending on your vendor. I do most things with the 2", it seems to work well for most applications. I have a compound for engraving and 4" for cutting thicker material.
What is the reason you have to have more clearance? And how much more do you need?
These are C series that I use, lens placement within the tube and focus from nozzle distance.
If the lens is mounted in the lens tube, the focus distance will always be the lens → material distance no matter how far it is from m3. You can gain more of a gap by using a different nozzle.
The longer the focal length the greater distance and the greater the depth of field (focus).
My head looks like this… a bit different than yours.
I only have one setup where there is two lenses in the tube at the same time… so I’m not really following what’s in your post as far as how to use the three lenses they show. Can you post a link to their advertisement?
Same tube, different nozzle focus point… I’ve labeled mine… old mind is slow…
Might have to be a bit more concise about what you want for us to really help you.
Thank you, Jack. When engraving tumblers on my chuck the two mounts where the handle mounts sits higher than my focus point. So the goal is to gain roughly 8-10mm in additiaonal Z clearance. simply replacing the nozzle cap may give me that. Is there a specific cloudray C nozzle that would work or it it a generic nozzle thread?

There are what I have purchased for mine…
This is the nozzle for a compound lens, but it’s shorter with a larger opening.
Can you move the lens lower in the tube?
I think these tubes can be flipped… mine can…
I was able to resolve this by ordering a different lens, different nozzle and cutting the tube shorter to allow it to retract more. Next machine will have more Z travel!
Thank you all for the help.
